Hi Curt, I like the 150 kHz tuning range. Mine is actually 170 kHz, which, of course, gives an average rate of 17 kHz per revolution with the 10 turn pot. I think this is still slower than the top rigs of my youth, which we though was quite good. I don't remember hearing complaints about the Drake and Collins tuning rates, which, IIRC, was in the 20 kHz per turn range. Of course, they did have larger knobs. I put a K2 knob on my K1, but I don't think that was necessary. I had to ream the hole to 1/4 inch. It should be possible to come up with a capacitor size that would give a 125 kHz. range, which I think would be ideal for 40 meters, but I haven't tried that yet.
